This is the code i use. it takes a control and sets the focus.
public static void SetInitialFocus(System.Web.UI.Control control)

{

if (control.Page == null)

{

throw new ArgumentException(

"The Control must be added to a Page before you can set the IntialFocus to it.");

}

if (control.Page.Request.Browser.JavaScript == true)

{

// Create JavaScript

System.Text.StringBuilder s = new System.Text.StringBuilder();

s.Append("\n<SCRIPT LANGUAGE='JavaScript'>\n");

s.Append("<!--\n");

s.Append("function SetInitialFocus()\n");

s.Append("{\n");

s.Append(" document.");

// Find the Form

System.Web.UI.Control p = control.Parent;

while (!(p is System.Web.UI.HtmlControls.HtmlForm))

p = p.Parent;

s.Append(p.ClientID);

s.Append("['");

s.Append(control.UniqueID);

// Set Focus on the selected item of a RadioButtonList

System.Web.UI.WebControls.TextBox rbl = control as System.Web.UI.WebControls.TextBox;

s.Append("'].focus();\n");

s.Append("}\n");

if (control.Page.SmartNavigation)

s.Append("window.setTimeout(SetInitialFocus, 500);\n");

else

s.Append("window.onload = SetInitialFocus;\n");

s.Append("// -->\n");

s.Append("</SCRIPT>");

// Register Client Script

control.Page.RegisterClientScriptBlock("InitialFocus", s.ToString());

}

}

In code-behind file, register JavaScript code to handle client onclick method of submit button:

e.g. btnSubmit.Attributes.Add("onclick", "OnSubmitTest");

in .aspx file, add following JavaScript method:

function OnSubmitTest()
{
if (null != document.all("txtTextbox"))
document.all("txtTextbox").focus();
}
